We had a total of 4:  1 group of 3 at about 6pm; then a solo just after 8pm.

The numbers have been steadily dwindling for years, but I was kind of expecting an uptick due to pleasant weather this year.  The oddest thing, though, was the 8pm visit.  Usually those are reliably teenagers. This one was maybe 7 or 8 - with parents chaperoning from the sidewalk.  I'd never seen that contingent out that late.
